The slimline design and silvery-grey finish of Viewsonic’s ViewBook will prompt inevitable comparisons with Apple’s MacBook Air - reviewed here. The ViewBook is only about half the price, though, so Viewsonic is obviously hoping to attract people that can’t manage the MacBook Air’s hefty price-tag.

Eh?

"...the 1.3GHz clock speed is a mite feeble for a fully-fledged laptop PC – especially one that costs more than £600."

Actually it's pretty reasonably priced and well in line with other C2D CULV based machines like the Acer 3810 Timelines which it most closely resembles in specification, and those CULV machines are more than adequate for general office-y type stuff.

Acer 3810TZ

The spec isn't as good, it's no doubt worse build quality, and it doesn't look as good. I am writing this from my Acer 3810TZ and I have to admit, for £450, this is the best laptop I could find. 8 hours of battery (I've had 11 hours with on / off browsing).

£150 less, twice the ram, same size HDD, same CPU, better build, and better looks. I don't regret buying this laptop at all.
